How you gain weight is no mystery. You gain weight by consuming more calories than you burn off in the course of a day. The excess calories, if not used by the body for energy, muscle building, or some other metabolic process, is stored as body fat. It’s stored as fat in case there is a future shortage of calories.

Much like you put excess junk you have around the house into a closet for storage, your body stores excess calories you haven’t used as body fat for future need.

The problem is, if you continue to eat the same amount of calories (or more) every day, there never is a future need and your body simply continues to store the excess as fat.

If excess calories are the culprit of weight gain, than the answer to achieving weight loss has to do with calories as well. You have to reverse the process that caused you to gain weight. You have to eat less calories.

I do not necessarily mean eating less food. I mean eating fewer calories, which is different.

There are two ways to have an impact on calorie expenditure in your body. Either eat less calories or burn more of them during exercise. I do not recommend going to extremes on either one of these but rather doing a little bit of both. When you diet and severely restrict calories, your body goes into a defense mode and begins to hold onto stored body fat.

While on a typical “diet” your body senses possible famine and holds onto body fat in case of future need. Also, your metabolism slows down because there’s not as much food to burn through and utilize.

So a drastic, sudden drop in calories is definitely not the way to achieve long term fat loss results.

Besides, how long could you possibly go on a restrictive diet before the feeling of deprivation makes you give in?

That is why diets traditionally do not work. You eat restrictively for a couple weeks and indeed have some success with weight loss.

But soon the diet becomes much too restrictive and you go back to the older, less restrictive way of eating. When the less healthy, less restrictive lifestyle comes back, so does all the weight you lost.

If you are trying to lose fat by dieting, you are always going to be in a position of playing “catch up”.

What I mean by this is, when you come off from a restrictive diet, you are going to “catch up” and eat all of the foods you felt deprived of. Instead of eating moderately and sensibly, the feelings of deprivation cause you to consume much more food than you normally would have if you weren’t dieting.

You’ll lose some weight on a diet and then gain it all back. Hence the term “yo-yo
